Spherical Plain Bearings

Spherical plain bearings are the ideal solution for mechanical systems where oscillating movement and angular misalignment are part of the design. These high-performance bearings are designed to provide consistent performance in demanding environments, offering flexibility, durability, and excellent load-handling capabilities.

A spherical plain bearing, also known as a spherical bushing or ball joint bearing, features an inner ring with a spherical convex outside surface and an outer ring with a corresponding concave inner surface. This unique construction allows the bearing to rotate and pivot freely within its housing, making it perfect for applications involving heavy loads, shock absorption, or constant misalignment.

Unlike rolling-element bearings, spherical plain bearings rely on sliding motion between the inner and outer rings. This design enables them to handle radial, axial, and combined loads—especially in slow-moving or oscillating systems.
